What each comparison means (3)
- Bourns SRP1038A-R36M: Same inductance, 0.36 µH vs MAZO 0.36 µH. Saturation current 60 A (20% drop) vs MAZO 50 A typ. (30% drop), rated on different bases so not directly comparable; heating current 31 A (40 °C rise) vs MAZO 30 A typ. (40 °C rise). DCR 1.2 mΩ max vs MAZO 1.2 mΩ max. Body 11 × 10 × 3.8 mm vs MAZO 11.5 × 10.3 × 4 mm, MAZO 0.2 mm taller. Land pattern close to MAZO's: two 3.5 × 4.1 mm pads 5.4 mm apart vs MAZO two 4.1 × 4.1 mm pads 5.4 mm apart (pad width differs by 0.6 mm). Verdict: replaceable with design margin (Idc about 3% lower at 40 °C rise, DCR equal). Before switching, verify brands define Isat/Irms differently: check the real peak current and allowed temperature rise, height clearance, the land pattern against both drawings and test samples.
- Würth Elektronik 744373680036 (WE-LHMI 1040): Same inductance, 0.36 µH vs MAZO 0.36 µH. Saturation current 44.5 A (10% drop) vs MAZO 50 A typ. (30% drop), rated on different bases so not directly comparable; heating current 36.2 A (40 °C rise) vs MAZO 30 A typ. (40 °C rise). DCR 1.2 mΩ max vs MAZO 1.2 mΩ max. Body 11 × 10 × 3.8 mm vs MAZO 11.5 × 10.3 × 4 mm, MAZO 0.2 mm taller. Land pattern close to MAZO's: two 3.5 × 4.1 mm pads 5.4 mm apart vs MAZO two 4.1 × 4.1 mm pads 5.4 mm apart (pad width differs by 0.6 mm). Verdict: replaceable with design margin (Idc about 17% lower at 40 °C rise, DCR equal). Before switching, verify brands define Isat/Irms differently: check the real peak current and allowed temperature rise, height clearance, the land pattern against both drawings and test samples.
- Vishay IHLP4040DZERR36M01 (IHLP-4040DZ-01): Same inductance, 0.36 µH vs MAZO 0.36 µH. Saturation current 60 A (20% drop) vs MAZO 50 A typ. (30% drop), rated on different bases so not directly comparable; heating current 31.5 A (40 °C rise) vs MAZO 30 A typ. (40 °C rise). DCR 1.4 mΩ max vs MAZO 1.2 mΩ max. Body 10.8 × 10.16 × 4 mm vs MAZO 11.5 × 10.3 × 4 mm. Land pattern differs from MAZO's: two 4.953 × 3.175 mm pads 5.842 mm apart vs MAZO two 4.1 × 4.1 mm pads 5.4 mm apart (overall span differs by 1.408 mm). Verdict: replaceable with design margin, pads need checking (Idc about 5% lower at 40 °C rise, DCR lower, less conduction loss). Before switching, verify brands define Isat/Irms differently: check the real peak current and allowed temperature rise, the land pattern against both drawings and test samples.
How the figures are compared
Isat and Irms follow each datasheet's own definition, shown after the figure. MAZO figures are typical values from its spec table.
Recommended pads: pad width × pad length, then the gap between the two pads, from each datasheet, compared with MAZO's.
Same footprint, other values
Same 11.5 × 10.3 mm body, by inductance. Check the height before swapping.

Selection and use
How to select
Choosing inductance
L ≈ (Vin − Vout) × Vout ÷ (Vin × fsw × ΔI), with ΔI at 20–40% of the output current. The series covers 0.15–100 µH in one body, so changing the value needs no new layout.
Saturation current Isat
the current at which inductance falls about 30%; keep the peak current below it.
Heating current Idc
the current that raises the part about 40 °C above a 25 °C ambient; ambient plus rise stays within 125 °C.
DC resistance
sets the conduction loss. Typical 0.5–315 mΩ across the series; use the maximum for loss budgets.
Height
Max 4.0 mm. Not AEC-Q200: for automotive designs use VCMA-1040, same size.
